Polvo a Lagareiro is a Portuguese dish of whole octopus simmered until tender, then roasted with a generous amount of olive oil until the tentacles crisp at the edges, served over smashed potatoes doused in the same olive oil. You make it by gently simmering the octopus low and slow until fork tender, then finishing it in a hot oven with olive oil, garlic, and roasted potatoes.
The name comes from lagar, the traditional Portuguese olive oil press, and the dish reflects a rural cooking style built around new, freshly pressed olive oil poured generously over simple ingredients. It's found on menus across Portugal, but it's especially associated with the country's olive growing regions, where good olive oil isn't a garnish, it's the point of the dish.
Octopus has a reputation for turning rubbery, but that only happens with the wrong cooking method. The real technique is a long, gentle simmer that breaks down the connective tissue before any high heat touches it.
What Actually Matters
Simmer the octopus low and slow, at a bare simmer rather than a hard boil, for at least 45 minutes to an hour depending on size, until a knife slides into the thickest part of a tentacle with no resistance. Boiling it hard and fast, or under cooking it, is what makes octopus tough and rubbery. Only after it's fully tender should it go into a hot oven, where the high heat is just there to crisp the exterior, not to finish cooking the inside.
Polvo a Lagareiro Recipe
Serves 4. Prep time: 15 minutes. Cook time: 1 hour 15 minutes. Total time: 1 hour 30 minutes.
Ingredients
- 2.5 pounds whole octopus, cleaned
- 1 onion, halved
- 2 bay leaves
- 1.5 pounds small new potatoes
- 2/3 cup olive oil, divided
- 6 cloves garlic, thinly sliced
- 1/4 cup chopped fresh parsley
- Salt and black pepper, to taste
Method
- Bring a large pot of water to a bare simmer with the onion and bay leaves. Add the octopus, reduce heat so the water barely bubbles, and simmer 45 minutes to 1 hour, until a knife pierces the thickest tentacle with no resistance.
- Remove the octopus and let it cool slightly. Preheat the oven to 425 degrees F.
- Meanwhile, boil the new potatoes in salted water until just tender, about 15 minutes. Drain and lightly smash each one with the back of a spoon or a fork, just enough to crack the skin.
- Arrange the potatoes in a roasting dish, drizzle with a third of the olive oil, and season with salt and pepper. Roast for 15 minutes.
- Cut the octopus into large pieces, separating the tentacles.
- Add the octopus pieces to the roasting dish with the potatoes, scatter the garlic over the top, and drizzle with the remaining olive oil.
- Roast for 12 to 15 minutes more, until the octopus edges are crisp and lightly browned.
- Scatter with parsley and serve immediately, spooning the pan juices over the top.

Tips, Variations, and Storage
Frozen octopus actually works well here, since freezing helps break down some of the muscle fibers before cooking. Leftover octopus keeps in the fridge for up to two days and reheats well in a hot skillet with a little more olive oil. Use the best olive oil you have for the final drizzle, since it's a defining flavor of the dish, not an afterthought.
Frequently Asked Questions
How do I know when the octopus is done simmering?
A knife or skewer should slide into the thickest part of a tentacle with no resistance. If it still feels tough, keep simmering and check again in 10 minute increments.
Should I use fresh or frozen octopus?
Either works well. Frozen octopus that's been thawed is actually a common choice, since the freezing process helps tenderize it.
Do I need a cork in the pot, like some recipes suggest?
That's a folk tradition without real evidence behind it. A gentle, low simmer for long enough is what actually tenderizes the octopus.
Can I grill the octopus instead of roasting it?
Yes, after simmering until tender, you can finish it on a hot grill instead of in the oven for a smokier flavor, following the same timing.
What wine pairs well with this dish?
A crisp Portuguese white, like a Vinho Verde, complements the olive oil and octopus nicely.
